DEVICE FOR REMOVING THE SEDIMENT FROM GASOLENE.

Specification of Letters Patent.

Patented Nov. 14, 1905.

Application filed December 3, 1904. Serial No. 235,335.

To all whom it may concern:

Be it known that we, HAROLD D. VVATER- HOUSE and FREDERICK W. GREEN, citizens of the United States of America, and residents of Quincy, in the county of Norfolk and State of Massachusetts, have invented certain new and useful Improvements in Devices for Bemoving Sediment from Gasolene, of which the following is a specification.

This invention relates to pipe-strainers, and has for its object the production of a strainer which can be inserted in a line of pipe through which gasolene and other materials of that nature pass. This strainer is designed to cause the gasolene or other material passing through the pipe to take an irregular or tortuous course through the strainer, in transit passing through a screen or other similar device, by which the impurities in the gasolene or other substance may be removed therefrom and collected in a sediment chamber beneath said screen.

It consists in certain novel features of construction and arrangement of parts, which will be readily understood by reference to the description of the drawings, and to the claims, to be hereinafter given.

Of the drawings, Figure 1 represents a vertical section of a pipe-strainer embodying the features of this invention. Fig. 2 represents a horizontal section of the same, the cuttingplane being on line 2 2 on Fig. 1. Fig. 3 represents a horizontal section of the same, the cutting-plane being on line 3 3 on Fig. 1; and Fig. 4 represents a vertical section of the same, the cutting-plane being on line 4 4: on Fig. 1.

Similar characters designate like parts throughout the several figures of the drawings.

In the drawings, represents a casing which is provided with two parallel vertical chambers 11 and 12, communicating at the bottom, as at 13. An inlet pipe 14: communicates with the upper end, of the chamber 11, and in direct line therewith a pipe 15 communicates with the chamber 12 at the top thereof. Immediately beneath the pipe 15 is an annular shoulder or lip 16, projecting into the cylindrical portion of said chamber. Against the under side of this shoulder 16 a screen 17 is held by means of a hollow cylindrical plug- 18, tapped at 19 into the lower end of the casing 10. The casing 10 is provided with an annular passage 20, surrounding the hollow cylindrical plug 18, said passage 20 connecting with the inlet-passage 11, while at the same time it communicates through openings 21 in said hollow cylindrical plug with the interior thereof. The plug 18 is provided with a projecting lip 22, between which and the end of the casing 10 is interposed a packing-ring 23.

Ordinarily the pipes used for the passage of gasolene and similar substances become clogged by means of impurities contained therein and oftentimes prevent the successful operation of the motors to which said material is being transmitted. Where vertical screens have been used on a line of pipe, while they separate some of the impurities from the gasolene or other substances, at the same time the impurities are usually collected at the screen and soon clog it up, so that the gasolene is prevented from passing through. The object of'the present invention is to obviate this difficulty and to insert a screen in the line of pipe in such a manner as to .permit the screen to separate the impurities therefrom as the gasolene or other substance passes therethrough and at the same time so locate the screen as to keep it from becoming clogged by these impurities, while provision is made also for a receptacle 24 in the bottom of the screw-plug 18 to collect the sediment.

Inorder to accomplish this, it is obvious that it is necessary that the screen 17 should be horizontal in avertical chamber or passage and that the gasolene and other substance to pass through the screen should be directed thereto from beneath. In this manner all the light impurities in the gasolene will be separatedby the screen, and in the jarring which takes place in the motor of a boat or carriage these impurities will be shaken from thescreen and droppedinto the receptacle 24 in the bottom of the plug. The heavier impurities as they pass from the inlet-pipe 14: through the passage 11 will collect in the receptacle 24 in the 'bottom'of the plug and will not rise in the chamber 12 a sufiicient distance to reach the screen 17. This is also true of any water which might be contained within the gasolene.

The strainer is designed in such a manner as to provide a receptacle of sufiicient size to contain a greater quantity of gasolene or other substance than can readily pass through the outlet-pipe 15, the object of this being to secure a storage of sufiicient gasolene or other substance to produce a sufficient supply to the motor to continue its operation when the main feed of the gasolene or other substance is cut off for any reason, as in a heavy seaway in the case of a motor mounted in a boat or the tipping of a carriage when the motor is mounted in a motor-vehicle.

The object of the annular passage 20 around the tubular plug 18 is to cause the gasolene or other substance passing from theinlet-passage 11 to this annular passage 20 to pass therefrom in all directions through the openings 21 in the plug 18, the various streams thereof uniting at the center of the plug in such a manner that the heavy impurities will be forced downwardly, while the gaseous portion will be permitted to rise and pass through the screen 17.

The plug 18 is tapped into the casing 10 at 19, so that it may be readily removed at any time to clean out the heavy dirt and water in the receptacle 24 or the light dirt which may remain upon the screen 17, this cleaning process being consummated without disturbing in any way the line of pipes 14 and 15.

By making the strainer so that the pipes 14 and 15 are in line one with the other the strainer can be much more readily set up than could be done otherwise.

It is believed that the operation of this invention will be thoroughly understood without any further description.

Having thus described our invention, we claim- 1. A pipe-strainer comprising a casing having a vertical chamber, a horizontal outletpipe communicating with the top of said chamber, a hollow screw-plug provided with a closed end tapped into the bottom of said chamber, a wire screen interposed between said plug and said outlet and extending over the open end of said plug, an annular passage around said plug near the bottom of said chamher and communicating with the interior of said plug, and an inlet extending from a point near the top of said chamber and communicating therewith near the bottom thereof.
